Frequently asked questions:

What are the chemicals used in water treatment?

There are many different chemical formulas used to treat the water cycle,
determined by the treatment process and which harmful substances are
found in the water. These include: flocculants, polymers, biocides,
membrane antiscalants, and more.

What are the chemicals used in industrial water treatment?

A wide range of water purification chemicals are used to in the industrial
water treatment cycle, including antiscalant chemicals, cooling and boiler
chemicals, wastewater chemicals, flocculation and coagulation chemicals.

How are chemicals removed from water?

A common method to treat water is with a filter, which removes impurities
from water with either physical barriers or chemical and/or biological processes.

What is the process of flocculation?

Flocculation water treatment is a chemical filtration process, where flocculants
(chemicals that stimulate water purification) cause clot-like masses of unwanted
sedimentation and particles in water (a ‘floc’). This ‘floc’ can then be removed
from the water more easily.

What chemical is used for flocculation?

Flocculants depend on which substances are to be removed from the water.
Examples include: aluminium sulphate, aluminium chloride, sodium aluminate,
ferric sulphate, ferrous sulphate, ferric chloride, ferric chloride sulphate, hydrated
lime and magnesium carbonate.

Can you use Chlorine for water purification?

Another common water purification method is chlorine water treatment, which is
the process of adding chlorine for the disinfection of drinking water and killing
germs in the water cycle.

Aquamarine is making every drop count.
You can too.

Why is water purification important?

Globally, the supply of clean water is a critical challenge to all, with a growing demand as a result of its finite supply.

A sustainable and clean water source is fundamental for both the world’s population and its economy to prosper.

Aquatech has 30+ years’ experience in the water purification industry, developing industrial and municipal water treatment solutions to overcome water-scarcity challenges.
